A Dogen quote which is in the article:"The volumes of the Sutras are the whole body of the Tathagata. To do prostrations to the volumes of the Sutras is to do prostrations to the Tathagata. To meet the volumes of the Sutras is to meet the Tathagata."(Shobogenzo, Nyoraizenshin – The Storehouse of the True Dharma Eye, The Whole Body of the Tathagata)

Most people probably wouldn't expect to hear Soto Zen Buddhists praise the sutras, but intelligent Soto Zen Buddhists realize that they are also more generally Mahayana Buddhists, and therefore, they respect Mahayana texts and symbols.
